Combine and sort results

This change introduces (experimental and not very clean) combining of results. It might be worth writing a disjoint angle range class to get cleaner code here, as the while loops at the end are quite far from being beautiful.
In addition the output ranges are sorted by their lower border. I'm using Lambda expressions for this, so C+11 is required.
Also, this is currently completely untested.
